摘要
Abstract
The general process of JPEG compression is described and the parallel working methods of Blacfin533 are analyzed.By using the Blackfin instruction set,the JPEG compression based on Loeffler algorithm fast 1D-DCT is realized to reducte the computing capacity and the computing time.The result shows that JPEG compression speed meets real-time monitoring conditions.关键词
